The LiRichFCC project will explore an entirely new class of materials for electrochemical energy storage termed “Li-rich FCC” comprising a very high concentration of lithium in a cubic dense packed structure (FCC). The process by which energy is stored in these materials constitutes a paradigm change in the design of battery materials and involves unexpected and surprisingly effective mechanisms: instead of storing lithium ions by intercalation into a stable host, lithium ions are populating and vacating lattice sites of the material itself. This new principle allows for unprecedented energy and power density compared to other battery materials and may revolutionize the use of batteries in applications involving a need for supplying large amounts of energy and power from small spaces.

Li-rich FCC materials have just been discovered by one of the partners of the consortium, and the possible chemical compositions, properties, and charge storage principle associated with this new materials class are far from being understood. Thus, it is the aim of the project to explore and optimize possible compositions, synthesis methods, structural properties and dynamics of Li-rich FCC materials through an interdisciplinary approach involving predictive computational work, advanced chemical synthesis and high-end characterization. An important focus of the project will further be to evaluate the use of these materials for electrical energy storage and to identify potential other uses for Li-rich FCC materials that cannot be foreseen today.

The project is based on the long-term vision to develop a novel class of materials into practical use, involving foundational aspects in S&T with breakthrough character, high novelty and risk, as well as a broad, interdisciplinary approach.
